14 Claims.

This invention relates to improvements in sink mountings for installing a standard fiat flange type sink in an opening in a drainboard or the like.

It is an object of the invention to provide improved mounting means particularly adapted for rigidly securing a sink of the flat flange or flat rim type in an opening in a linoleum covered drainboard or the like and providing a watertight seal between the sink and the drainboard.

It is a more specific object of the invention to provide a sink mounting for the purpose described which comprises a generally T-shaped sealing member having a top portion which covers the space between the edge of the sink and the drainboard and having a downwardly extending web portion which is positioned between the edge of the sink and the drainboard, a plurality of angular clamping elements adapted to be detachably interengaged with the sealing member in spaced relation around the edge of the sink which clamping elements have adjustable clamping screws in their inwardly projecting legs and a plurality of angular securing lugs having one leg adapted to be rigidly attached to the drainboard and having the other leg slotted for receiving in clamping relation the clamping screws in a predetermined number of the clamping elements, the clamping screws in the remaining clamping elements being adapted to engage the sink rim in clamping relation. f

It is a further object of the invention to provide a sink mounting comprising a generally T-shaped sealing member of the type described wherein an inwardly directed narrow ledge formation is provided on the bottom thereof and wherein a slot is provided in the bottom surface of the top thereof and cooperating L-shaped clamping elements adapted to be positioned with one leg in interengaging relation with the bottom ledge formation and the slotted top of the sealing member.

These and other objects of the invention will be apparent from a description of the preferred form thereof which is shown by way of illustration in the accompanying drawing, wherein:

Fig. 1 is a top plan view of a sink installed in a drainboard with a mounting means embodying the principles of the invention;

Fig. 2 is a bottom view of a corner of the sink installation to an enlarged scale;

Fig. 3 is an enlarged isometric sectional view taken generally on the line 3--3 of Fig. 2;

Fig. 4 is an enlarged isometric sectional view taken generally on the line 4-4 of Fig. 2;

Fig. 5 is a perspective view of a portion of the sealing ring member;

Fig. 6 is a perspective view of one of the clamping elements;

Fig. 7 is a perspective view of one of the drainboard attaching elements;

Fig. 8 is a section illustrating the sealing member attached to the sink rim;

Fig. 9 is a section similar to Fig. 8 showing one of the clamping elements in position for engagement with an attaching element on the drainboard;

Fig. 10 is a section illustrating one of the attaching elements rigidly secured to the drainboard; and

Fig. 11 is a perspective view of a modified form of the drainboard attaching element.

In the form of the invention which is illustrated in Figs. 1 to 10 of the drawings there is provided a mounting and sealing ring member It for securing a sink II in position in an aperture I2 in a drainboard I3. The sink II is a standard type having an outwardly directed top rim or flange I4 and the drainboard I3 is a conventional plyboard structure having a linoleum top H5. The drainboard I3 may be of any depth since the fixture is adapted to be used in drainboards of varying thicknesses. The aperture I2 is larger than the periphery of the sink II to provide space for the sealing member Ill.

The sealing member I6 is preferably constructed of an extruded section of metal such as aluminum or similar material having sufficient resiliency to permit bending in order to install the same on the flange I4 of the sink II. The member I0 is formed into a split ring to surround the four sides of the sink and is T-shaped in cross section providing a vertically positioned web portion I6 terminating at the top in an inwardly extending flange I1 which is positioned over the edge of the sink rim I4 and an outwardly extending flange I8 which is positioned over the linoleum top I5 of the drainboard I3. The edges of the flanges I1 and I8 may be rounded or feathered as desired to insure a relatively smooth surface between the sink II and the drainboard I3. The vertical web portion I6 of the member I0 terminates at the bottom in an inwardly directed flange or abutment ledge or shoulder I9 the upper surface of which slants inwardly and upwardly to provide a somewhat hook-shaped formation. At the top of the web portion Iii a groove or channel forming slot 20 is provided in the bottom surface of the flange I! immediately adjacent the web to provide a downwardly extending abutment surface in opposed relation to the upper portion of the web it. The recess or groove formation 25' extends throughout the length of the member i6 and may also be formed by any downwardly projecting ridge or shoulder formation on the bottom of flange ll.

A plurality of angular clamping elements or lugs 2i are provided for cooperation with the member it. Each clamping element 2| is L- shaped to provide a vertical leg 22 (Fig. 6) and and a somewhat shorter horizontal leg 23. The leg 23 is provided with a threaded aperture at 2 3 which is adapted to receive in threaded engagement a bolt 25. The bolt 25 is inserted from the bottom and projects upwardly. The clamping elements 2i are interengaged with the member Ill by positioning the leg 22 against the inner face of the web portion [5 with the upper end of the leg 22 extending above the abutment formation provided by the groove in the bottom surface of the flange ll and with the lower surface of the leg 23 engaging in' abutting relation on the top edge of the abutment shoulder 59. The lower surface of the leg 23 may be grooved or provided with a shoulder to more positively engage with the hook-line formation is on the bottom edge of the web it, the elements being, of course, free to slide along the vertical web it of the frame it. The leg 23 is directed inwardly of the member H1 and the bolt 25 may be adjusted upwardly to engage the lower surface of therim M of the sink 1 l as shown in Fig.8.

A plurality of angular drainboard fastening or what above the leg 33 and which is adapted to be positioned in engagement with the lower surface of the drainboard [3. The flange member facilitates positioning the element 32 on the drainboard and also relieves the fastening screw of some of the vertical stress caused by the bolt 25 which engages the slotted leg 33 of the element.

, It ,will be appreciated that while the mounting structure is herein specifically disclosed for use in securing a sink in a drainboard it is capable of being used in mounting or securing any device of a similar character in an apertured drainboard or other top member where installation conditions are similar and that while specific reference is made in the claims to a sink and a drainboard other devices of an equivalent nature are intended to be included in the scope thereof. While specific details of construction and materials have been referred to in describing the form of the invention illustrated herewith, it will be understood that other details of construction and other materials may be resorted to Within the attaching elements 26 are provided each of which spirit of the invention.
